Using CamelCase for the single-instance (singleton) objects -- None, NotImplemented, and Ellipsis -- highlights their special nature, i.e. that we check for them by identity. "not_implemented" would look like just another local variable. I wish that NotImplemented had been made a keyword, just like None, True, and False. I see no value in being able to assign to this name. It invites confusion. For Ellipsis we at least have `...`. -- https://mail.python.org/mailman/listinfo/python-list
